mongoexport 命令异常方便简单强大!
连接数据库:
jkmiao@jkmiao-ipin:~$ mongo 192.168.1.xx:xxx/jd_58tc_raw
1. 导出10条数据到标准输出
mongoexport -h 192.168.1.xx:xxxxx -d jd_58tc_raw -c jd_raw_38 -f 'jdJob' -q '{"jdJob.age":/25岁/}' --limit 10
2. 到文件
$ mongoexport -h 192.168.1.97:27027 -d jd_58tc_raw -c jd_raw_38 -f 'jdJob' -q '{"jdJob.age":/25岁/}' --limit 10 --pretty -o jd_58tc_output.json 2016-01-31T16:30:58.612+0800 connected to: 192.168.1.97:27027 2016-01-31T16:30:58.716+0800 exported 10 records

mongoimport -h localhost:27017 -d jd_raw -c jd_58tc_raw --drop ./jd_58tc_output.json
